Longtime Palm fans are gonna want to lock the doors and turn down the lights -- our friends at PhoneScoop just got the first demo of Motion Computing's Classic Palm OS emulator for the Palm Pre. Palm OS apps can be installed by just dragging the .prc files over the Pre in mass storage mode, and they're run as though they were on an SD card. There's no tethered HotSync, although there's a compatibility mode of some kind and apps will be able to pull data down over the air. Check the video after the break, including a demo of ePocrates, which we know a lot of potential Pre owners are interested in.
